First aid skills are very important in the process of disaster medical rescue methods. Some first aid skills is rarely applied in clinical work at ordinary times, resulting in relevant medical personnel grasp of these skills being not enough skilled. This training method combined with the sim-ulator, has the characteristics and advantages of being close to the real, operational and repeatable. The main training program consists of 6 basic skills such as ventilation, hemostasis, bandaging, fixing, handling, basic life support. By simulating the real disaster scenario and simulation cases, we have targeted a single first aid skills training and multiple comprehensive ability training of first aid skills to trainees. To evaluate the training effect we have examined the individual skills of our trainees, with excellent performance as the goal, and in the comprehensive skills ability assessment we have paid attention to the emergency team's team cooperation ability. By the application of comprehensive simu-lation training and evaluation, the trainees can master all kinds of first aid skills in a short period of time.

Objective To study the expression and pathologic significance of CD147,cyclophilin A (CyPA)and cyclophilin B(CyPB)in psoriatic lesions.Methods Immunohistochemical method was ap- plied to detect the expression of CD147,CyPA and CyPB in skin specimens of 15 patients with psoriasis pustulosa(PP),20 patients with progressive psoriasis vulgaris(PPV),and 20 patients with inactive psori- asis vulgaris(IPV).Immunoreactivity intensity distribution index(IRIDI)was calculated to assess the expres- sion intensity of CD147,CyPA and CyPB.Results CD147,CyPA and CyPB were detected in all speci- mens.The IRIDI scores of CD147 and CyPA were significantly higher in keratinocytes of psoriatic lesions than in those of the control specimens(all P0.05).The IRIDI score of CyPB in T lymphocytes of PP lesions was significantly elevated than that in PPV lesions,which was in turn higher than that in IPV lesions(all P0.05).Conclusion CD147,CyPA and CyPB may play a role in the occurrence and development of psoriasis.

This paper described the results of the optimal method for preparation and extraction of lectin from Phaeoporus obliquus(Pers ex Fr).(J.Schroet).We determined the optimal buffer solution using the ag-glutination test with 2% hare blood cells.The optimal extraction process included the following parameters that were conformed by optimization analysis: material-water ratio,extraction time,concentration of sodium chloride and the pH value.The results are that the agglutination indexes of POL using TBS and PBS extrac-tion buffer were 64 and 16,respectively.The optimal extraction process is that,the material-water ratio was 1:50,the extraction time was 20 h,while the concentration of sodium chloride was 0 mol/L and pH was 8.0.The agglutinability of POL was 256 examined by this method.The optimized extraction process is stable and practicable,which may supply some basis for the application of the lectin from Phaeoporus obliquus in immunoregulation.

AIM:To investigate the influence of matrine (MA) on the phenotype switching of mouse mono-cytes and alveolar macrophages induced by bleomycin ( BLM) .METHODS:All mice were randomly divided into normal saline (NS) group, BLM group, BLM+NS group and BLM +MA group.The mice were administered with BLM at 2.5 mg/kg via oropharyngeal instillation .The mice in BLM+MA group were treated with MA (15 mg· kg-1 · d-1 ) by oral gavage following BLM administration .The mice were sacrificed on days 3, 7, 14, and 21.The lungs were removed for pathological analysis .The circulating monocyte subsets and polarization state of bronchoalveolar lavage fluid ( BALF)-de-rived alveolar macrophages were analyzed by flow cytometry .RESULTS:The results of HE and Masson trichrome staining in BLM and BLM+NS groups exhibited classical pathological stages of lung fibrosis , including acute inflammation phase and later fibrosis phase .Compared with BLM +NS group, MA treatment alleviated the inflammatory response and the de-gree of fibrosis induced by BLM (P<0.05).There was a rapid change of circulating Ly6Chi monocytes and its magnitude was positively associated with the pulmonary inflammatory response .An expansion of M2-like alveolar macrophages was positively correlated with the magnitude of lung fibrosis .Moreover , MA treatment partially normalized the phenotype switc-hing of monocytes and alveolar macrophages .CONCLUSION:Matrine treatment attenuates BLM-induced pulmonary injury partially via modulating the phenotype switching of monocytes and alveolar mocrophages .

OBJECTIVETo investigate the association between the polymorphism of vitamin D receptor (VDR) gene start codon (Fok I) and bone mass accrual, and assessing if such an association could be modified by physical activity in Chinese adolescent girls.

METHODSA total of 228 premenrche Chinese girls (9-11.5-years-old) were recruited for 2-year study. Bone mineral densities (BMD) at the total body, total left hip (including femoral neck, trochanter, intertrochanteric and Ward's triangle area) and lumbar spine (L1-L4) were measured by dual energy X-ray absorptiometry. The Fok I polymorphism of VDR gene was detected with PCR-RFLP.

RESULTSThere remained 176 available subjects in our cohort when 2-year study was completed. No significant association was observed between Fok I polymorphism of VDR gene and percentage change in BMD at all sites. Girls with FF genotype had lower percentage change in total left hip BMD (THBMD) and femoral neck BMD (FNBMD) than girls with Ff + ff genotype only in low physical activity(< 1197 kJ/d), and physical activity was associated with percentage change in THBMD and FNBMD only in FF genotype group.

CONCLUSIONThe Fok I polymorphism of VDR gene should have significant interaction effect with physical activity on bone mass accrual in Chinese adolescent girls. Girls with FF genotype in low physical activity would be the potential risk population for low bone mass accrual, and high physical activity would be of benefit to gain higher bone mass accrual for girls with FF genotype.

To investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 pathway and the growth of gastric cancer cell lines at different GHR expression status, the eukaryotic expression vector targeting human GHR (pGPU6/GFP/Neo-shGHR and pGPU6/GFP/Neo-scramble) was constructed and transfected into MGC803 cells by Lipofectamine 2000. Stable expressive cell lines were obtained by G418 screening. The expression of GHR was analyzed by Western blotting. After being stimulated with rhGH, cell growth was detected by MTT assay. Cell cycle and apoptosis were examined by flow cytometry. The components of JAK2/STAT3 signaling pathway were detected by Western blotting. There is no significant difference of GHR expression between MGC803 and pGPU6/GFP/Neo-scramble-transfected cells (named as MGC803-NC) (P > 0.05). Compared with MGC803, the GHR expression in pGPU6/GFP/Neo-shGHR-transfected cells (named as MGC803-shGHR) decreased significantly (protein decreased 50%). The cells were treated with rhGH at 0, 150 and 300 ng x mL(-1), the growth rate of MGC803 and MGC803-NC increased significantly, PI and the number of G2/M phase cells all increased significantly, and apoptosis decreased significantly. Western blotting revealed that the expression of pJAK2 and pSTAT3 was up-regulated after being treated with rhGH in MGC803 and MGC803-NC cells. In contrast, similar change was not observed in MGC803-shGHR cells. Knockdown of GHR gene may decrease the sensitivity of gastric cancer cells to rhGH, and down-regulating of components of the expression of JAK2/STAT3 signaling pathway may be the potential mechanisms.
